Pmmdi-eb. 2a, 1939 PATENT OFFICE PORTABLE CASING TRANSFORMABLE INTO ATAISLE FOR SEWING MACHINES Ramon Casas Robert, Barcelona, SpainApplication December 9, 1936, Serial No. 114,958 In Spain February 15,1936 7 Claims. (01. is-aaz) The invention has among its objects toprovide aportable casing in which to place and to carry portable sewingmachines and which is also adapted to be used as a work-table by aconvenient changing of the positions of its component parts in suchmanner that the table is disposed at the level of the plate of themachine on which the garment or other object to be sewn is placed.

The use of a portable casing of this kind to form the casing of thesewing machine avoids the use of additional tables for increasing thesurface on which the garment may be placed, so that the machine itselfneed only be provided with a platform of reduced area in the form of anelongated arm, so that certain articles or parts of garments of atubular form, such as sleeves, stockings, or like articles, can

be sewn.

The invention is diagrammatically illustrated byway of example in theaccompanying drawings:

Figure 1 is a perspective view of the outside of the portable casingaccording to the. invention.

Figure 2 is a view corresponding to Figure 1, assuming that the cover isslightly raised away from the base.

Figure 3 is an elevation of the portable casing without the sewingmachine and disposed horizontally, the view being taken looking from thebottom upwards.

Figure 4 is a side elevation illustrating the method of opening thecasing.

Figure 5 is a perspective view of the casing opened out ready for use asa table or platform for a sewing machine.

Figure 6 is a view corresponding to Figure 5,

.but showing the sewing machine fitted to the opened casing serving as aplatform.

Figure '7 is an elevation showing the base of the sewing machine adaptedfor the mounting thereon of the casing serving as a cover for themachine.

Figure 8 is a sectional elevation of the base of the machine showing thelocking device for the casing as well as the lower part thereof.

The portable casing according to the invention is released or locked inrelation to the base of the machine by means of a bolt I. After releasethe casing can be raised by means'of the handle 2 from-the base 3 of themachine, which in the closed position, forms the base of the casing, sshown in Figure 2.

To the base 3 are secured the component parts 24 where they are retainedby means of latches 1, I which are subject to the force of springs l0secured on a common shaft 9 on which may 15 be set the key 6 for openingthe casing. These latches l move elastically when the projections 8 areintroduced into the notches or slots 24, 24, since they are set topresent surfaces at a slightly oblique angle to the path of movement 20of the projections. By reason of this arrangement the key 6 alone isadapted to open the casing.

The cover II-I2 formed as a parallelepiped which serves to enclose themachine is divided 25 into two leaves; the leaf II is less in depth thanthe leaf l2, the difference being represented by the thickness of apanel [3. The two leaves II, l2 are held together at the opening of thecover by two hinges l4, H, which permit 30 of the leaves being movedthrough 180, as is clear from Figure 4.

The hinge I5, by which the panel I3 is hinged to the leaf l2, alsopermits of a relative movement through 180 so that the panel may come 35to rest on the leaf II when the latter is in the unfolded position, andmay equalize the height of the leaf II with that of the leaf I2, thusforming a work-table when the two leaves are opened out in thehorizontal positions, (see Figure 5). 40

In pivoting about the hinge IS, the panel l3 uncovers one wall of theportable casing. In this wall is formed a slot I6 in which may bereceived the platform 22 and the lowr part of the machine I, as is shownin Figure '6. When 45 the leaves II and I2 are brought together toreform the portable casing in its rectangular form, the panel I3 isrevolved about the hinge l5 to cover the slot l6 by laying against thewall in which the slot is formed, as is shown in Fig- 50 ure 4. Thus thepanel I3 protects from surface wear the surface of the table formed ashas been described, by the two extended leaves II and I2.

The opening in the upper or end wall of the leaf l2 in continuation ofthe slot I6 is closed by a shutter I! hinged at one side of the saidopening to swing outwardly upon the adjacent part of the said end wall.

Feet such as It support the table assembly (Figures and 6) so that itrests at the level of the platlorm .32 through which the needle 0! thesewing machine reciprocates.

In order to swing the leaves H and I2 to the Open position, the handmust first be introduced inside the cover forming the body of theportable casing to grip a handle I] fixed to a spindle carrying bolts,so that the bolls may be operated to release the two leaves, which uptill then have been held by the bolts so that they may be separated. Onthe separation of the leaves the shutter I9 is also released from theclosed position in which'it has been retained by a metal member 25 whichis adapted to extend inwardly on the inner face of the end wall of theleaf When the leaves ii and I2 are separated, it thus becomes possibleto raise a shutter l9 which up till then had held the panel l3 by meansof an annular member of angular form, so that the said panel can beswung on the hinge l5. In order to close the portable casing; thereverse procedure is followed. The opening of the shutter i9 allows themachine 4 to be fitted into the slot i6 when it is desired to use theopened out casing as a work-table.

At 23 is disposed a drum or similar member on which is wound the flexsupplying the electric current for the working and lighting of themachine.

I claim: a

1. A casing for portable sewing machines, comprised by a base member anda hollow bell-like cover removably connected to the base member, thesaid cover consisting of two parts meeting along a plane normal to thebase member and pivotally connected together to revolve relatively. intoalignment about an axis that is transverse to and disposed at the mouthof the cover, the said parts of the cover when in alignment and restingupon the edges which when the cover is closed are in contactconstituting a hollow table of an inverted tray-like form, the uppersurface of which is formed by the side walls of the parts and the endwalls of which are respectively formed by the two parts of the top ofthe cover.

2. A casing for portable sewing machines provided with a base member andan elevated work platform, comprised by the base member of the machineand a hollow bell-like cover removably connected to the said basemember, the said cover consisting of two partsmeeting along a planenormal to the base member and pivotally connected together to revolverelatively about an axis that is transverse to the mouth of the coverinto alignment, the said parts of the cover when in alignment forming ahollow table of an inverted traylike form, the end walls of which arerespectively formed by the two parts of the top of the cover, the sidewall and end wall of one of the said parts being slotted to permit thehollow table to be disposed in position in relation to the sewingmachine to dispose the work platform as part of the said slotted sidewall.
